Trailing zeros after a decimal point are not normally written. As trailing zeros have been written they must be significant; thus 101.0100 has 7 sig fig.

For a multiplication or division, you should check how many significant figures each of the factors has, and take the least of them. This is the number of significant figures you should keep in the answer.

significant figures
It is not so simple to explain in few words; see the link below.
0.00684 has three significant figures The product of 7.6 x 1.246321 has two significant figures. 28623 has five significant figures. 1.20000 x 10-19 has six significant figures. Trailing zeroes after a decimal point are considered significant. In scientific notation, only the numbers before the multiplication symbol are considered significant.

The rounded value is 10. See also the links below. * * * * * However, there is no such thing as the correct number of significant figures (sf). SF depends on the context as well as the SF of the numbers used to compute the value.
The rules for identifying significant figures when writing or interpreting numbers are as follows: 1. All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). 2. Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. 4. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
The average z score chart lists z scores with three significant figures. For example, you can find the z score -1.81 on the chart, but not -1.812 or -1.818. In the case that you wish to look up a z score with more than three significant figures, round it to three significant figures and then use the chart. OR You can also use a calculator if you wish to get more accurate results. The link for calculator is mentioned below.
